T0 all whom it may concern: Be it knownthat l, CHARLES F. HALDE- MAN, a-citizen of the United States, residing.

.ensilage cutters,fin which the material is conveyed to the silo direct from the machine.

The objects yof my invention are, first, to provide for the proper removing from Ythe cutter` the Iout materialy or ensilage without intermediate mechanism located between the trated in the accompanying. drawings, al-y though my invention may be embodied in a K variety of other mechanical forms,-theconstruction illustrated being chosen-by way of example.

lnthe accompanying` drawings: Figure 1 is a perspective view ofthe cutter, its casing and a portion of the fan or blower chamber, the top orhinged portion `of the casing being shown in its open position. Fig. 2 is a longitudinal verticalsection, showing the differentparts properly arranged witli'reference to each other, with the upper section of the casingy in its open position. Fig. 3 is a section taken on line 3 3 looking in the direction indicated by the arrows, the hinged top or cover beingshown in dotted lines `in its opened position.' l

Similar numerals of. reference indicate corresponding parts in allthe figures of the 1n they accompanying drawing, 1V represents the frame which is constructedfin the usual manner, reference beinghad to properly attaching` my improvements. rThe frame, within itself forms no speciiicfpartof the present invention, except that afframe suoli as commonly used in fodder cutters-of the rotary cutting` head type must i necessa- Specification of Letters Patent.

rily be present or some equivalent structure. To the frame l are connected in anycon-- vement and well known manner the shaft Vbearing brackets 2, which shaft bearing shaft boxes does lnot differ largelyfrom corresponding parts commonly used in fodder cutters. Upon the power shaft 4 are located the driving wheel or pulley. 5, the knife carrying spiders or brackets 6 andthe fan or blower wheel-7, said parts all being properly mounted upon the power shaft 1l, and in suoli a manner that they will rotate with the power shaft; in other words all of the above parts being securely mounted upon the power shaft.y rEhe specific construction of the spider 6', the cutting. knives 8 andthe cutter bar 9 does not have to do with the present invention, except that they should be so constructed and arrangedfthat the various parts which do pertain to the present invention can be used in connection therewith. |The material designed to be cut is fed to the cutter head by means of an endless conveyer 10 or itsr equivalent, the lower andupper feed rolls 11 and 12, said parts being arranged in` the usual mannercommon to feed or-ensilage cutters and hence no detailed 'description is deemed necessary. The cutter head proper which is made up of the spiders 6, the knives 8 and the means for holding the knives in fixed. adjustmentis incased in a cylindrical casing preferably formed in two semi-circular sections hinged together. the purpose hereinafter described, the semicircular sections 13 and 14- are so formed that when the hinged section is brought into its closed position a tapered or lfrustum shaped casing'willbe produced. The semicircular section 13 is-held in lixed position in any convenient and well known, manner preferably by bolts such as15, and the upper section 14 hinged to the` top plate or bar 16, said upper section being so located and arranged that ivhen it is brought into a closed position the upperandlower sections will be Forin the usual manner and of the usual form and in which casing is locatedr the blower proper, which blower consists of the wheel 7, to`which wheel the fan blades 19 are attached. rilhe wheel 7 is formed of sufficient weight to provide a suitable balance wheel by which a sullicientmomentum is produced i to prevent any sudden stopping or jerking of the cutter head proper and the fan proper. It will be understood that the fan casing is of the usuall construction and is provided 'with the usual discharge or elevating spout,

but as such construction is well known and understood,the same is not illustrated.

In use the material designed to be cut and conveyed to a silo is fed to the cutter proper in the usual manner, the cut material in the rst instance is contained within the casing of thepcutter head made up of fixed and hinged casing sections. The large end of the cutter head casing is located directly opposite the eye or opening of the fan casing,

which is the air intake opening of the fan or.

blast chamber.

It will be understoodthat the fan blades are to'be so arranged that a suction from or through the cutter head casing will be produced, the air being drawn into kthe fan chamber and expelled or blown out through an ordinary control; or elevator pipe. For' rthe'purpose of producing a strong current of locating the cutter head casing directlyy op-' air .through the cutterhead casing and toward the fank or blower casing, the intake opening 20 is provided, through which opening the air is free to enter and move toward and into the fan chamber. v v

hF or the purpose of allowing air to enter the top or upper part of the chamber within which the cutter head is located the end plate'21 ofy the hinged section 14 is provided vwith a vseries of perforations 22, through which perforationsairr is free to pass. By

, pered, the larger end being located against the side of the fan casing, said cutter head casing being substantially of the same size and shape, as the eye or opening of the fan chamber. It is well understood that the cutter heads of machines of the class to which 'y this 'pertains ai'e formed of some length and the material is spread upon the feed apron and in order to allow proper `clearance the size ofthe cutter head chamber should be fan chamber and the cutter head chamber as above described the suction of the fan is direct, and no device or devices intermediate the cutter head casing and the fan casing are required, the material being withdrawn from the cutter head casing by the direct action of the fan.

For the purpose of holding the upper section la when in a closed position the fiange 18 is provided, which flangey is secured in any convenient and well known manner to the side of the fan or blower casing.

The power shaft 4: is extended into the fan chamber and the bearing for said shaft near the fan is located between the fan proper and the cutter head by which arrangement the shaft is prevented from springing at the cutting point or in other words two bearings are provided for the power shaft, both bearings located close to the cutting head. It will also be understood that by locating the bearing as above described that the power shaft does not need to be disturbed in any way when it is necessary to remove the fan casing, thereby providing means for removing the fan casing and fan and enabling me to ship the device in a knock down condition, thereby reducing vthe bulk of the machine.

Having fully described my invention what I claim as new and desiie to secure by Letters Patent, is-

1. In a device of the character described, the combination of a cutter head mounted upon a shaft, a casing adapted to inclose said cutter head, a fan chamber and a fan located within said chamber and upon the cutter head shaft, said cutter head casing being tapered, the larger portion being located adjacent the fan casing.

2. In a device of the character described, the combination of a cutter head mounted upon a shaft, a fan casing, a fan located within the casing and mounted upon the cutter head shaft, a cutter head casing adapted to inclose said cutter head and the air intake end of said casing provided with air passages, said cutter head casing being tapered from the fan casing toward the air intake end thereof.

3. In a device of the character described, thecoinbination of a cutting mechanism consisting of a cutter head and a cutter bar, said cutter head mounted upon a shaft, a casing adapted to inclose said cutter head, said casing being of frustum shape, the outer reduced. extremity of said casingv being proln testimony that claim the above, I vided with a perforated Wall, a fan chamber have hereunto subscribed my name in the provided With an opening. the opening in presence of tvvo Witnesses.
